to be upgradable to provide software options such as 12-lead ECG
measurement and interpretive analysis,
to be upgradable with a third mode of operation: (3) Exercise mode
for exercise stress testing, and
to provide for the optional transmission and reception of ECG data to
and from a central ECG cardiovascular information system.
NOTE
Pediatric population is defined as patients between the ages of 0 and
15 years of age.
Arrhythmia detection is provided for the convenience or automatic
documentation.
The MAC 1600 device is NOT intended:
to be used during patient transport,
to be used for intra-cardiac applications,
to be used as a vital signs physiological monitor, or
to provide alarms for Arrhythmia detection.
The Arrhythmia detection mode is provided for the convenience of
automatic documentation.
It is not necessary to remove the ECG electrodes prior to defibrillation;
the patient signal is defibrillation-proof.
Use silver-silver chloride electrodes. A defibrillator discharge may cause
stainless steel or silver electrodes to retain a residual charge, which
could cause a polarization that will block the acquisition of the ECG
signal for several minutes.
We recommend using non-polarizing disposable electrodes with
defibrillation recovery ratings as specified in AAMI EC 12.3.2.2.4
(SilverTRACE family of electrodes). AAMI EC12 requires that the
polarization potential of an electrode pair does not exceed 100 mV
5 seconds after a defibrillation discharge.
If other electrodes are used, disconnect the patient cable from the system
before delivering the defibrillation shock.
NOTE
If excessive DC voltages are present at the electrode, then a message
will appear indicating a Lead Off condition.
ADS (cubic spline correction) and the FRF algorithm cause a signal delay
of approximately 2 seconds; therefore they should be disabled if the
patient has to be defibrillated while the ECG is being recorded.
